Q: How to Ensure Proper Wheel Bearing Service and Installation on a Lincoln Mark LT?
A: Service and repair operations for wheel bearing and wheel hub assembly should start with NEUTRAL gear position while using a hoist to support the vehicle. Allowing the brake hose to support the caliper and anchor plate assembly will cause damage so mechanics should use mechanic's wire to support the assembly while removing the bolts. Reinstallation should be performed by tightening caliper and anchor plate assembly bolts at 200 Nm (148 ft. lbs.). The wheel hub nut needs to be taken off next but when installing the part tighten it at 400 Nm (296 ft. lbs.). Remove the brake disc/wheel bearing and wheel hub assembly while avoiding lubrication on the wheel spindle threaded end. After cleaning the thread-end area of the wheel spindle with the recommended solvent the technician will follow all reverse steps to perform an installation. The replacement process requires using brand-new components with matching part numbers along with applying specified torque values for fastener retention of vital suspension systems.
Q: How to service the rear wheel bearing and axle shaft seal on a 8.8-inch ring gear on Lincoln Town Car?
A: The first step to service the rear wheel bearing and axle shaft seal on Ford 8.8-inch ring gear is removing the axle shaft. You should check the vent of the axle housing for blockages when the wheel bearing oil seal starts leaking. Remove the oil seal from the axle tube while thoroughly protecting the seal bore along with the tube. Carefully examine both the rear wheel bearing along with the axle shaft to check for signs of wear or damage. Extraction of the rear wheel bearing becomes necessary when using a Slide Hammer in combination with an Axle Bearing Remover tool. The new rear wheel bearing requires application of rear axle lubricant before using the Axle Shaft Bearing Installer to set it in place. Use Axle Shaft Oil Seal Installer to install the new wheel bearing oil seal by applying long-life grease to its lip. Finally, reinstall the axle shaft.
Q: How to Service and Repair the Front Wheel Bearing Hub on Lincoln Navigator?
A: The front wheel hub repair process should begin with disconnecting the wheel speed sensor electrical connector. Assume NEUTRAL gear position for the vehicle while positioning it on a hoist. Strip away the wheel speed sensor harness bracket bolt before taking the harness out from its retainers. Reinstall this harness later at 12 Nm (9 lb-ft). Avoid allowing the caliper and anchor plate assembly to depend on the brake hose since this poses a danger to maintenance. Properly support the caliper with mechanic's wire while tightening bolts to 200 Nm (148 lb-ft) torque specifications. Remove the brake disc followed by removing the four bolts securing the wheel bearing and wheel hub assembly and then extract the wheel bearing and wheel hub before tightening all bolts to 150 Nm (111 lb-ft). The wheel bearing and wheel hub installation requires you to remove both the wheel speed sensor bolt and wheel speed sensor which should be tightened with 18 Nm (13 lb-ft). After wheel bearing and wheel hub reinstallation of original components it is essential to install a fresh O-ring seal for the assembly. The installation will finish by completing the reversed removal process.
